      What is the captured database version and mode of depoyment?

      (E.g. on-premises, with a specific cloud provider, etc.)

      • on-premises

      What behaviour do you expect?

      • Message level in the Connector log output when an error occurs is WARN or INFO.

      What behaviour do you see?

      • The message level of the Connector log output when an error occurs is ERROR.
      • Error messages are output to the log on the PostgreSQL side.

      Do you see the same behaviour using the latest relesead Debezium version?

      (Ideally, also verify with latest Alpha/Beta/CR version)

      • I do not have an answer to this question.

      Do you have the connector logs, ideally from start till finish?

      (You might be asked later to provide DEBUG/TRACE level log)

      • No.

      How to reproduce the issue using our tutorial deployment?

      • I do not have an answer to this question.

      Feature request or enhancement

      For feature requests or enhancements, provide this information, please:

      Which use case/requirement will be addressed by the proposed feature?

      • I do not have an answer to this question.

      Implementation ideas (optional)

      • I do not have an answer to this question.
